Mazda E engine (original) (raw)

The iron-block, alloy head E family was an evolution of Mazda's xC design. It was released in June 1980 with the introduction of the first front-wheel drive Mazda Familias and Ford Lasers. Some later variants of the E5-powered Mazda Familia and Ford Laser in Japan incorporated a full-time 4WD drivetrain. All E engines were chain-driven, 8-valve SOHC. Notable features include siamesed cylinders, aluminium rocker arms and pistons, thin block walls, and single valve springs - all in the interest of reducing weight.
